Nutrient limits in diets for growing dairy goats

Dry matter intake and nutrient requirements of young growing dairy goats were reviewed in this paper to derive nutrient limits applicable for diet optimization through minimum cost linear programming. The diets offered to growing goats should be optimized from both nutritional and economic view. To...
